9K38 Igla

The 9K38 Igla, NATO SA-18 Grouse, was developed as a Soviet man-portable air-defense system to replace and improve on Strela-series MANPADS. The program focused on better resistance to countermeasures, improved target discrimination, and greater effectiveness against low-flying aircraft and helicopters. Its portability made it a tactical and proliferation concern beyond regular air-defense units.

Igla is built around a compact launch tube with an infrared-guided missile and reusable gripstock equipment. Its design allows small teams to cover air approaches without vehicles or heavy radar support. The weapon's tactical value lies in concealment and mobility, while its limitations include short range, weather dependence, and the need for target acquisition by the operator.

The Igla family was exported widely and remains in many inventories. Its presence can alter air operations by forcing helicopters and low-flying aircraft to use altitude, flares, tactics, or standoff weapons. The system's legacy is not only technical but operational: portable air defense makes even small units a threat to aircraft at low altitude.
